# Viena Latina

Static, self-hosted, trilingual blog for the Latin American community in
Vienna — Hugo + Decap CMS + Gitea + Woodpecker CI on a single Hetzner CX22
(Nuremberg, DE). Replaces the previous WordPress + Polylang + synchronous
DeepL stack.

```

## Languages

Spanish is the authoring language; German (`/de/`) and Brazilian Portuguese
(`/pt-br/`) siblings are generated by CI as reviewable git commits. Siblings
pair by filename basename:

```
content/post/mi-articulo.es.md      ← authored in Decap
content/post/mi-articulo.de.md      ← written by scripts/translate.py
content/post/mi-articulo.pt-br.md   ← written by scripts/translate.py
```

Set `manual_translation: true` in a sibling's frontmatter to freeze it —
CI will never overwrite it again.

### Frontmatter contract

```yaml
---
title: "Mi artículo"
date: 2026-07-31
lang: es
manual_translation: false   # set true on *.de.md/*.pt-br.md to freeze
categories: [Gastronomía]
---
```

## Translation flow

1. Publish `*.es.md` in Decap → one git commit, no waiting on DeepL.
2. Gitea webhook fires Woodpecker.
3. `scripts/translate.py` diffs the push, translates changed `*.es.md` via
   DeepL (`tag_handling=html`, protected community terms), writes the
   siblings, and pushes them back as a bot commit
   (`translations@vienalatina.com`).
4. `hugo --minify` builds, `rsync --delete` deploys, Caddy serves.

Any DeepL error fails the pipeline visibly (red X, one-click retry) —
no half-translated sets ever ship.

## Server setup

Full command-by-command walkthrough: **[docs/server-setup.md](docs/server-setup.md)**.
The Caddyfile and Docker Compose files it uses live in [infra/](infra/).

## Local development

```sh
hugo server          # http://localhost:1313
```

## CI secrets (Woodpecker → repo settings → secrets)

| Secret | Value |
|---|---|
| `deepl_api_key` | DeepL free-tier key (500k chars/mo) |
| `gitea_push_token` | Gitea token for the translations bot user, repo write access |

The repo must be marked **trusted** in Woodpecker so the deploy step can
mount `/var/www/vienalatina.com`.

## Decap CMS

`static/admin/config.yml` uses the Gitea backend. Register an OAuth app in
Gitea admin (redirect URI `https://vienalatina.com/admin/`) and put its
client ID in `app_id`. The Decap JS bundle is downloaded at build time into
`static/admin/decap-cms.js` (gitignored) — zero third-party requests at
runtime.

## GEO/SEO surfaces

- `hreflang` + `og:locale(:alternate)` + JSON-LD `BlogPosting`/`Blog` with
  `inLanguage` — `themes/vienalatina/layouts/partials/seo-head.html`
- `robots.txt` AI-crawler allowlist — `static/robots.txt`
- `llms.txt` — generated at build time from `layouts/index.llms.txt`
- `sitemap.xml` — Hugo native, multilingual

## One-shot content migration

```sh
pip install requests html2text
python scripts/wp-to-hugo.py https://<old-wp-site>
```

Converts every WP post (with Polylang siblings) to
`content/post/<slug>.<lang>.md`, downloads images into `static/uploads/`,
and preserves existing slugs. Spot-check ~10 articles before committing.
Add Caddy 301s for WP URL patterns that don't map cleanly
(`?p=123`, `/categoria/...` → `/categories/...`).
